3. RTK setup options
There are several different RTK-GNSS options, which are supported in Dewesoft. RTK can be established
either with:
●Internal RTK-GNSS receiver:
○Any Dewesoft GNSS and DS-IMU2 device can be upgraded with RTK licence which
provides accuracy up to 1 cm.
○DS-IMU1 already comes with RTK licence by default in hardware versions 7.0 and above.
The RTK on DS-IMU1 is a single frequency L1 RTK.
●and GNSS/INS platforms (Genesys, OxTS).
For additional information about devices, check the technical specifications on our website.

3.1. Features
●RTK license upgrade - any Dewesoft 100 Hz GNSS and DS-IMU device can be upgraded with
RTK.
●Dewesoft provides all hardware accessories needed for the RTK upgrade - base station,
antennas and 3G and RF modems for data transmission between car and base station.
●Internal RTK-GNSS receiver achieves up to 1 cm horizontal and 2 cm vertical accuracy.
●Portable and rugged instruments.
●Expandable with SIRIUS slices or DEWE-43.
●Easy-to-install.
●Easy-to-use.
●Many additional synchronized data sources like video, CAN, FlexRay, XCP, OBDII, multi sensor
inputs, advanced counter inputs.
●RTK technique can also be used for accurate relative positions with the use of a movable base
station. The absolute accuracy of this system is as good as is the solution of the moving base
station. However centimeter accuracy between the base station and the rover is achievable.
Movable base techniques are used in ADAS (Advanced Drivers Assistance) tests where relative
position between two vehicles has to be measured.

3.2. Requirements
Due to the nature and accuracy of RTK solution there are certain requirements that have to be met to
acquire and maintain the RTK fix solution:
●RTK licence installed on used devices (for up to 1 cm accuracy)
●only satellites that are visible to both the base station and the rover can be used in RTK
calculation, RTK receivers normally require at least 5 common satellites,
●the best accuracy is met with clear sky environment and in a good weather conditions - signal
obstructions that cause multipath or cause loss of satellite visibility can cause a loss of RTK fix
and partial or even full recalculation of cycle ambiguity,
●RTK solution is valid only in the range of 15-20 km around the base station, this can be
increased to the maximum of 80 km with the use of a network of RTK base stations NRTK.

4. Scope of supply
4.1. Base station
DEWESoft directly provides a complete base station based on
DS-VGPS-HS device. As a base station device can also be used
S-BOX with embedded 100 Hz Topcon receiver. Both
mentioned devices need to be upgraded with RTK licence to
provide accuracy up to 1 cm.
4.1.1. Other informations
Base station has autonomous operation and its configuration
and monitoring is resolved via Bluetooth.

4.2. Rover with internal GNSS
Dewesoft provides different options that can be used as a rover devices:
●DS-VGPS-HSC,
●embedded 100 Hz S-BOX receiver,
●DS-IMU1,
●DS-IMU2,
●DS-VGPS-HS (only as a standalone rover - see 4.2.1. Synchronization).
4.2.1. Synchronization
-DS-IMU1, DS-IMU2 and DS-VGPS-HSC have an option of synchronisation the measurement data
with any other connected Dewesoft hardware (e.g.: SIRIUS, …).
-DS-VGPS-HS has no sync output, therefore it cannot be directly synchronized with any other
device. If it is used as a rover, it has to be used as a standalone device, where it sends a PPS
signal to the PC.
Important
Usually a computer device is used to collect measured data from the rover. As a computer you
can use either your laptop or a S-BOX with an additional display.
The table below shows the minimal needed equipment for the Rover, where the system can be
extended with various options. Systems in general differ from one to another according to different
setups, so for the exact configuration please contact your regional sales representative.

4.3. Power supply options
Both the base station and rovers need to be powered by a power supply. DEWESoft provides various
power supply options such as:
-Battery Pack 2i or 4i (BP2i, BP4i),
-Cigarette lighter plug cable.
BP2i/BP4i is the most frequently used power supply device. It is used in case you want to remain your
measurement running after a vehicle is already shutted down. If you do not need such measurement
data, you can simply use cigarette lighter plug cable.
4.5. System expandability
You can expand your measurement system by adding DEWESoft DAQ devices and have completely
synchronized measured data between them. For example if you need to have the data from video, CAN,
FlexRay, XCP, OBDII, multi sensor inputs, advanced counter inputs.
Most frequently used devices in RTK applications are:
-SIRIUS and
- DEWE-43.
